The ‘Oscural Dox’ is a book shrouded in mystery. Some who have used it have rose to great power; others have been damned to early deaths. All who come into contact with it are touched in one way or another… And now, it belongs to me, Scott Jackson.

At least, that’s what I told myself as I looked again at the bound cover, a leathery and old tome that I’d found in an old box at a garage sale. Only the title was visible, and I knew it would be the perfect gift to freak out my religious friend Laura Bennet, a good way of getting her back for her efforts to get me hooked on Catholicism.

I’m a good Christian—really, I am—but I have no interest whatsoever in a religion that asks for constant donation. I realize that running a church requires cost, but I can’t abide some members of the order living like kings while others stay true to their vows of poverty.

Of course, Laura didn’t see it my way, and she kept harping on about how much good it would join me to join an organization I had no interest in. I thought that I was done with frat rush-esque events after college!

I grinned up at the door to my room as she walked in, a patronizing grin on her face. “So tell me, what’s this all about?” She asked, her eyes widening as she saw the book in my hands.

“Now, I know that this isn’t really your deal, but I found this ancient dark book… And ever since then, I’ve been hearing these whispers in my head, and I figured that you should read it too; tell me if it’s just—”

My carefully planned speech fell to shambles as Laura screamed, pulling out the crucifix she wore around her neck and practically knocking off her glasses in the process. “Get that thing away from me!” She yelped, jumping atop my bed instead of bolting for the door.

Funny how some people get dumb when they’re scared. I smirked and lifted the book to her, as though I was holding some religious tome. “Come on, Laura… Join us. We’re so lonely in this one body, we need to spread; we need to feed!” I licked my lips and Laura whimpered, squeezing her eyes shut.

“O God in heaven, sanctify this vessel, cleanse it of evil. Sanctify this vessel. Sanctify this vessel. Sanctify this vessel.” Laura whimpered, repeating herself over and over again, her hand stretched out and her eyes tightly shut.

I decided to give up the act, instead sniggering at her actions. “You’re quoting ‘Dominion’ now, aren’t you?”

Her eyes opened quietly and she looked at me with distrust. “S-Scott?”

“The one and—ow!” I yelped as she hit me in the face with one of my pillows. And another. And another. I rubbed my forehead gingerly, then squeaked as she picked up my titanium alarm clock. “Hey! If you throw that at me, I’ll die!” I yelped, covering my face instinctively.

Thankfully, that seemed to be enough to make her come back to her senses. She laid the clock down gingerly… Then picked up a fallen pillow and proceeded to beat me with it.

“Don’t… Ever… Scare… Me… Like… That… Again!” She punctuated each word with several heavy thumps, and I laughed heartily, grabbing the pillow as she finished.

“Are you done?” I asked, looking her in the eyes.

“Yeah.” She nodded, her chest still hiking as she breathed in and out deeply. I felt a little guilty; she’d always kept herself in good shape, so her hyperventilation had to be from fear, not exertion… But I’d already gotten in this much trouble, so I might as well finish the prank.

“Good. Because I’d really like to read this thing now.” I looked at her with a smile, only to yelp again as she hit me over the head once more. “What was that for?” I exclaimed, my eyes wide as I rubbed the back of my head. That one actually hurt!

“No reading from the book. I have enough of a hard time trying to make you Catholic; I don’t even want to think of how hard it will be when you’re possessed.” She pouted, adjusting her glasses up the bridge of her nose.

“One: I’m not going to be possessed. Two: I’m going to read from this regardless of your presence, so wouldn’t you rather be here just in case?” I asked, dropping the tome on my lap and flipping open to a random page.

“N-no!” She squeaked. “This is what happens to people in scary movies, don’t you dare read from that, you dummy!” She whimpered loudly, her hands moving to close the book in my lap.

I laughed and held her back, deciding to play with her a little. To my surprise, the books were written with English letters, making it perfectly easy for me to speak the contents despite a language barrier. “En tux gladio tradus nom…”

Laura struggled more, her hands waving madly. “No no no, no reading from the book! Please, no more, I’ll leave, don’t!”

“Gra valis velis proxam hux…” I continued, chuckling at how distraught she looked. Honestly, it was just a book! What kind of harm had ever come from reading a book?

“Please, please! I’m begging you, this is really freaking me out!” She whined loudly.

“Et proxam gris kul damone.” I finished the sentence with a smirk, feeling Laura’s struggles cease the moment I stopped reading. “There, did anything bad happen? No.” I looked up to find her gazing blankly ahead, her mouth slightly agape.

“Um…” I blinked in surprise. It wasn’t like her to play along, so I began to worry I’d given my friend a heart attack. “Laura?”

She blinked, working her jaw for a moment. Then she looked to me with a smile on her face that I’d never seen before, something sultry yet jubilant. “Laura? No… Try Lilith.” She smirked, a dark look in her eyes.

“Um…” I started, looking at her with confusion, my heart staring to pick up its pace. “Okay, you got me.” I laughed nervously as her head twitched slightly.

“Got you? No, not yet…” Laura looked down to her chest with a small frown, then looked back up to me. She smiled, cupping her breasts in her hands and squeezing them. “I think that we’d need to fuck first, yes?”

I blinked, moving back uneasily. “Hey… You got me. You can stop now, I’m really starting to worry…” This was nothing like her; what was she doing? Trying to scare me? Because she was succeeding!

I gulped nervously; then gasped as I looked at her body. She was changing, her breasts beginning to swell in her hands as she gazed at me with something that could best be described as ‘hunger’. A low and husky purr emerged from her throat a she looked at me, tongue snaking from her lips to moisten them.

“L-Laura?” I squeaked with worry, whimpering as she trailed both of her hands to my groin. It wasn’t the gesture that worried me—it was the fact that the skin on her hands and forearms was beginning to crack and peel, turning a jet black.

It was like she was growing scaly claws, a full set of sharp and dangerous talons tipping her fingers. She flexed them, ripping through the seam along my shorts with ease, baring my penis to her. As she did, her eyes brightened and darkened simultaneously—her irises changing from brown to a blood red, and her sclera swirling with an inky blackness.

“I’m freaking out…” I squeaked, my heart racing as I tried to pretend that this was still some joke of hers, that she’d somehow bought some sort of high-tech contacts and we were on some reality TV show. But as her skin darkened to a rich blue, I realized that this nightmare was all too real.

“Poor thing, I know just the cure for that.” She whispered, trailing one of her sharp talons just along the underside of my shaft, bringing it all the way up to my sensitive tip. It was sinfully good, and my cock stiffened despite the horror in my heart.

Before I could respond, she dipped her head low and licked my cock, a deep blue tongue trailing saliva along my length. But it wasn’t human saliva, not anymore. No, whatever Laura’s mouth produced was an enticing lube that left an oddly cool and fresh sensation on my member, making it grow harder and harder.

Finally, I found words; though they were probably the dumbest thing I could say in that situation. “I didn’t take a shower since two days ago.” I blushed at how dumb I sounded but still tried to crawl away from the demoness—for surely she was a demoness.

“I know. You taste wonderful.” Was her reply as she stalked after me on all fours, her feet scuffing against the floor as she moved.

I looked over her shoulder to see that her legs were darkening from the knees down, covered in that same dusky enamel which covered her forearms. It was like a natural armor, and from the look of it she could still feel perfectly fine through the growths.

There was a faint sensation on my legs, and I glanced down to find that Laura—Lilith’s—top had somehow fallen on top of me. My gaze wandered up to drink in the sight of her bare upper body, her perfect large breasts swaying gently as she watched me like a cat would look at a mouse.

“That’s a good boy, eyes on the prize.” Lilith purred, moaning as she licked my cock again.

Even though I was scared out of my mind, this was also one of the sexiest things I’ve ever seen. I couldn’t help but feel turned on by how much she was getting off just by tasting my cock, and I watched as she dipped her head down once more, embracing my shaft with her plump lips.

This time I was the one to moan, a trail of pleasure arcing up my back. I looked down at the girl who was sucking me off with interest as her lips began to darken to a light shade of blue. And the azure glow didn’t stop there, spreading across her skin like she was being dipped in an inky bath.

I watched with horrified interest, my pulse racing as her hair changed shade to a vibrant purple and her ears drew to almost elven points. My friend was becoming a demoness! No, she was a demoness! Was there really any Laura left within her?

I began to suspect that the answer to that question was ‘no’; that I had pushed her too far and she really did have a heart attack, leaving her body open to possession… Or worse, that I’d evicted her soul from her form and shoved Lilith’s inside it.

To my horror, I realized that there was a part of me that didn’t care. Lilith’s lips were perfect; her mouth was like a warm haven for my aching cock! Could it really be that I was fine with losing my friend to this demoness; for having what was undeniably the best blowjob of my life?

I didn’t know the answer, moaning loudly as Lilith took all of my length deep into her throat, her tongue flicking against my balls as she continued to suck me off. It was heaven; it was more than heaven! I needed her so much; I needed this demoness!

I began to pump my hips, bucking them back and forth and fucking her throat. I tried to convince myself that it was an attempt to discomfort her; to have some sort of vengeance for my friend… But I knew deep down in my heart that it was really only just me giving into my lust; enjoying this too much.

I loved the tingling that her drool left around my length; hell, I loved how just having my cock in her mouth was making me drool uncontrollably! She moaned huskily with her every other breath and her skin took on a rich sheen of mint-scented sweat, making this blowjob a pleasurable assault on all five of my senses.

I almost didn’t notice as a black tail slid out from her spine, snaking past her pert ass and flicking from side to side. Her tail was glossy and sleek, and I shook with anticipation as her tail’s tip flared out, growing to the traditional spade-like shape seen in pop culture.

On the other hand, I certainly paid attention to the pair of black horns which she grew, large and curved things which flared up at their ends to sharp, ruby red points. I watched them come in, my heart hammering as I kept thrusting into her mouth, and before I knew what I was doing I’d grabbed one in each hand and used them to keep her head close as she sucked me off; to force myself as far into her as I could go.

Instead of whining with discomfort like I’d expected, she only let out an inhumanly loud and long moan, her eyes shut as she savored my dick. It was the sexiest sound I’ve ever heard and I responded to it by thrusting even rougher, my balls clenching as I hilted and withdrew myself from her time and time again.

Finally, I could bear it no more, and I gripped her horns and slammed her head back down onto myself. I grunted with my eyes tightly shut, grunting as I ejaculated within her mouth, spilling my seed down her throat.

It was the hardest I’ve ever came in my life, and I groaned with ecstasy as I continued to come, my balls aching as I continued to shoot my load into her, shooting more semen than I’d ever spilled in my life. It was so pleasurable, so incredibly perfect that it took me nearly a minute to realize that something was very, very wrong.

The cum wouldn’t stop spilling, and my balls more than ached now—they hurt! It was like they were being squeezed in a vise! I looked down, half-expecting to see Lilith’s clawed hand around my member. The actuality of the situation was far, far worse.

My scrotum was shriveling, like it was being deflated—and it felt like there was more of her mouth around my cock. A spike of fear shot through my heart as I realized that my cock was shrinking too—and that the flesh was being used elsewhere.

My chest felt like something was pressing out from the skin, like I was starting to be inflated with some warm and soft flesh. I whimpered, my mouth processing what I was growing before my mind did. “Breasts.” I whispered, blinking in surprise at how much lighter my voice sounded.

As the word passed through my mouth, they quaked in response and grew ever larger, making me shift my posture for the perfect pair. They were glorious double D’s, the same size which I’d often fantasized on my dream girl.

“Luscious, full ones.” Lilith agreed, my cock now small enough in her mouth that she could talk around it like a lollipop. I looked down to her with horror only for my gaze to turn to the last few seconds of my cock’s existence.

It shrank more and more, vanishing completely with just the slightest pinching. My balls followed suit, and I felt my smooth groin with shock, looking back up to Lilith with horror. “W-what did you do?” I asked, my voice still musically gentle.

“Hm? I’m making you my pet.” Lilith smirked, tapping me gently on my nose. “Or did you think that my services were free?” She evidently wasn’t expecting an answer, instead pressing three of her sharp fingers to my smooth groin.

Then she pushed. Her nails bit into my skin for only a second; then a slit formed along where she pressed; and just like that I was the proud owner of a new and needy pussy. I shook with sensation at the feeling of having a vagina, an incredible sensation that I never thought I’d experience.

It was like having a new set of muscles ‘down there’, an utterly alien organ on my body. I could feel her fingers slipping inside of me too, and unlike the calloused and hard digits I’d expected, these felt like they were flesh and blood—no, better than that!

I moaned, my pussy clenching hard around her fingers even as my hips flared and my sides pinched in, giving me an hourglass figure. “S-so good!” I whimpered, feeling her digits slip past my folds. It was like her talons had withdrawn the minute they entered me, giving her the ability to pleasure me even as a woman.

“What? You say that like you’re surprised.” Lilith smirked, pulling away from me for a moment, spreading her arms in an ironically cruciform fashion. I watched with wide eyes as a pair of wings slid form her back, a wet slurping sound heralding their growth.

They were featherless and blue, with leather like a bat’s. Each of them was tipped in a sharp talon, and they glistened with a faint sheen of sweat as she flapped them in the air, grinning to herself. She stood from me to flex her wings again—and this time the motion came with an added effect.

Small bands of light shimmered around her form, and I watched with wide eyes as they coruscated into a set of armor; the light fading to reveal that the plate’s actual color was a deep black wild golden trim and inlaid rubies.

Of course it also covered the bare minimum of skin, acting as lingerie as much as it did a proper set of protective gear. Not that I really expected anything more from her.

She grinned at me as though she could read my thoughts; then brought her fingers down to the codpiece of her armor. I watched with an abject curiosity as the metal began to twist at her direction, growing and forming what I realized had to be a phallus.

Sure enough, as details began to etch within the metal, I began to make out the distinctive bulges of veins; the flare of a tip. And there was a part of me that loved it; some insane part of my brain that couldn’t wait to feel it inside of me.

“Like it? It’s yours.” She trailed her fingers along the shaft of the strap-on, grinning back to me with a chuckle. “I mean, not really; but it’s a replica of it. After that little face-fuck, I figured you owed your new mistress a good fuck for real.”

“M-mistress?” The word sounded so good on my tongue that I couldn’t help but tremble with anticipation, my legs spreading while my mind remained in a daze. I blushed at the thought of her entering me, and a coquettish giggle escaped my throat.

I knew that it was insane, but I also knew that I didn’t care. There was just this part of my brain that wanted to be a needy slut; that ached for a life of servitude to the demon that had possessed my friend. Possession… Was that what was happening to me? “Am I… Being possessed?” I managed, voicing my concerns with a wavering feminine voice.

“In a sense.” Lilith looked down to me with a condescending grin on her lips, watching me with interest. “You’re giving into that innate base lust that so grips all of your kind; the sin which I and my kind feed on.”

I trembled at the thought of her ‘feeding on’ me, of her dipping her tongue past my gentle lips, into my love hole. It was a sinfully good daydream, and I found my hands drifting between my legs, my fingers dipping into my slit.

I swallowed hard, not having expected to make it this far; having thought Lilith would stop me, wanting to pleasure me with that phallic facsimile. But she only watched with a knowing smile on her face, a subtle nod encouraging me forward.

I nodded back, just now noticing how long my hair had grown in my transformation into a woman. But that was a thing of the past, my present full only with thoughts of pleasuring myself. I tossed my long locks out, slipping a finger past my lips with a squeak of excitement.

Just as I’d dreamed of, it was good—more than good, perfect! I let my middle finger enter the party, whimpering as my pleasure only increased, the extra stimulation making my toes curl with content. Moving on instinct, my thumb brushed over my clit and further stoked the fired in my heart.

“Ohh!” I moaned loudly, following it with an echoed moan just to hear my sexy feminine voice again. It was so good, so amazing! I moved my fingers in small gentle circles; worked on spreading and closing them; dipped them in as far as I could.

I was fingering myself! The thought was almost as enticing as the action itself, and I groaned with sheer ecstasy, my other hand lifting to my chest to massage my large breasts. They were just as soft as I’d thought, weighty in my hands and on my chest, yet gentle enough to be held and caressed.

I groaned louder, my back tingling; my knees tingling with the want, the need to come. It was a sinful pleasure that I didn’t know I needed, an aching in my soul that was desperate to be filled. I whimpered louder and louder, straining my back and pinching on my nipples hard as I tried to experience the rush of release.

It kept sweeping through me, and I dug in more desperately, trying to stimulate myself and bring about the climax that I so richly deserved. But no matter what I did, every attempt met with that same maddening emptiness, a hollow void that could only be filled with orgasm.

I spread my fingers as wide as I could, pressing deep into my walls and whining loudly, cracking an eye open to Lilith. “Why can’t I come?” I begged, closing my mouth to swallow the drool I didn’t notice building up.

“Mn? Whatever do you mean?” Lilith smiled, grinning at me with amusement. Her tail snaked from side to side, and she purred happily.

“Please! I can’t come! You know what!” I whimpered, tearing my left hand from my breasts to let it enter my hollow hole. I looked back to her, begging for a release that I couldn’t seem to achieve on my own.

“Well…” She tapped a finger against her succulent lips, its talon growing as she did. “I suppose I can… But you’ll need to give yourself to me; become my slave.”

“Anything, anything, just let me come! Please!” I whined loudly, slipping my hands from myself and spreading my legs as wide as I could. “Fuck me, fuck me!”

“If you insist.” Lilith purred, sliding onto my like a snake grips a tree. Her arms snaked around me; her wings covered us like a blanket; her tail gently trailed along my back. And best of all, her strap-on pressed against my lips; then past them.

I let out a loud moan of pleasure, louder than anything that I had uttered before. I didn’t care, my attention only devoted to the strap-on that was plowing my pussy. I groaned and thrust my hips against Lilith’s, a new tingling spreading out form my pussy.

I looked down to it with wide eyes, watching as the skin around my lower lips turned a rich blue; a royal blue in contrast to the light blue that decorated Lilith’s body. My eyes widened, but only for a moment. I grinned happily at the demoness, uttering a contented “Thank you so much, Mistress!”

“But she show has only begun, my pet.” Lilith purred, cupping my breasts in her hands and trailing her tongue around my areolas.

I hadn’t thought about how incredible it would be to have her lick me like that; to spread that fresh lube that was her spit along my body. As such, when the cool pleasure gripped my breasts, I whimpered loudly and squealed, clutching Lilith’s warm body to mine and kissing her feverishly.

Her breath tasted like both mint and male cum, my two favorite flavors. I drank it in, kissing her more and moaning as her tongue swept along the inside of my mouth. It was so good, so pleasurable! Better yet, kissing her like this was making my whole body turn blue, tingling with the sensation of change!

Lilith broke the kiss to look me in the eyes, and I mewled with distress. I needed her; I needed to be with her! I whined and tried to bring my plush lips to hers once more, only for her to place a finger on my lips and point down to my backside.

I followed her finger to blush madly at the sight of my tailbone extending away from the base of my spine. It was a sleek and blue tail, almost like that of a snake’s. I watched with surprise as it swept from side to side, enjoying this as much as I was.

Still, it wasn’t like Lilith’s, and I couldn’t help but ask why. “This tail… It’s not like yours…” I looked at her with a small pout on my face, wondering why my goddess hadn’t made me in her image.

To my surprise, she patted me on the head happily and grinned. “You’re rather smart for a dumb little demoness, you know?”

I blinked; then blushed at her compliment. “Thank you mistress!” I yelped with delight a moment later as she hilted the strap-on within my body, making me feel another crashing wave of pleasure.

“You’re my slave; how could you ever be on the same footing as I am?” Lilith hissed, her wicked smile dulling the cut of her words.

I nodded eagerly, my breath coming in short hitches as she truly began to plow me, her thrusts growing more and more intense by the second. “Y-you’re so rough!” I yelped, squirming as the blue skin finished covering me from head to toe.

My eyes burned; ears aching as they were tugged out to points at either side of my head, and I tossed my purpling hair out behind me with a wild smile. “I love it! Fuck me harder, mistress!”

“As you wish.” Came her response, and Lilith gripped me in both hands, her wings beating as she pulled me up to my feet just so she could slam my back against the wall.

I groaned loudly, eyes watering with delight at the feeling of her driving into me time and time again. My fingers and toes both curled, hardening into dark claws much like Lilith’s. Only again, mine were different: my forearms were ridged with tough enamel, and the backs of my feet lowered to sharp points, giving me a natural set of high heels.

“So good!” I howled, the sound tearing itself from my throat. To think that this morning I had been a human man! This body was so much better; so feminine; so sensational; so powerful! I tossed my head back and uttered a lecherous moan, rolling my neck and grinning with mad lust.

My skull cramped as horns grew out from it, four of them. Two were like a ram’s horns, curled around the sides of my head. The other two were long and narrow, like that of an impala. I loved each of them equally, especially when Lilith gripped me hard by them and pulled me from the wall to the bed.

Her strap-on pulled out from my cunt and I whined with protest, only to squeak in surprise as she spun me around, slamming a hand into my back to bend me over. My taloned fingers clutched at the plush bedspread; then dug into it as she hilted herself in me once more, hitting me deeper and deeper now that she was fucking me like I was a lusty bitch.

“Hnngoddess yes!” I howled, rearing my head back and screaming with pleasure as she grabbed onto my horns, using them to hold me as she fucked me harder and harder still. It was an insane bounty of sensations; a wealth of pleasure! Sweat beaded my form, soaking the sheets beneath me, and I whined with need, eyes tightly shut.

Lilith tugged my head to her lips and hissed into my ears. “Beg for me. Beg me to come like the slutty demoness you are.” It was the most romantic thing I’d ever heard in my life.

“Mistress, please! Please let your demoness come, let her spill over you, let her be your pet forever!” I begged, digging my talons deeper into the bedspread. “I’ll do anything, be anyone, fuck anyone, make me yours; just make me yours!”

“As you wish.” She whispered, and I tried to brace myself for what came next.

Of course, I was completely unprepared for it. To compare my last orgasm as a man to my first as a demoness would be like comparing a ripple in the water to a tsunami. I howled with lust, an insane rush of ecstasy coruscating along my back before finally bursting free in the form of a pair of blue wings, which beat frantically in the air to cool myself down.

I was burning up! This pleasure was like nothing I’d have ever thought to have had, and now I was held helpless in its sway! I whined loudly as sweat dripped down my face, my pussy clenched hard around the strap-on.

Then an aftershock hit me, and I began to hyperventilate as my pussy spilled over Lilith’s codpiece, my fluids matting down the sheets and even spilling onto my floor. It was incredible, it was perfect, and it was the end of my changes.

I fell onto the bed with an elated gasp, curling my new wings around myself for warmth. To my surprise, Lilith joined me a moment later, her tail snaking around my own and her wings enveloping the both of us.

I moaned with delight, cuddling back into her embrace. “Mistress, today was… was…” I struggled for words, my demoness’s brain nothing compared that of the being who now owned me.

“Just the beginning.” Lilith spoke softly into my ear. “Sleep.”

I did as asked, but even so was unable to miss her repeating herself. “Today was just the beginning.”
